Illinois Medicaid recipients have been limited to four prescription drugs as the state becomes the latest to cap how many medicines it will cover in the state-federal health insurance program for the poor.

Doctors fear the state's cost-cutting move could harm patients, who have to get state permission to go beyond the limit.

"We understand the state is trying to get its Medicaid budget under control, but our concern is it not be a hardship for patients and a hassle for doctors in the execution," says William Werner, president of the Illinois State Medical Society.
